class Sequel::BasicObject

:nocov: If on Ruby 1.8, create a Sequel::BasicObject class that is similar to the the Ruby 1.9 BasicObject class. This is used in a few places where proxy objects are needed that respond to any method call.

If on 1.9, create a Sequel::BasicObject class that is just like the default BasicObject class, except that missing constants are resolved in Object. This allows the virtual row support to work with classes without prefixing them with ::, such as:

DB[:bonds].where{maturity_date > Time.now}

Constants

KEEP_METHODS: The instance methods to not remove from the class when removing other methods.

Public Class Methods

const_missing(name) click to toggle source

Lookup missing constants in ::Object

# File lib/sequel/sql.rb, line 32
def self.const_missing(name)
  ::Object.const_get(name)
end

remove_methods!() click to toggle source

Remove all but the most basic instance methods from the class. A separate method so that it can be called again if necessary if you load libraries after Sequel that add instance methods to Object.

# File lib/sequel/sql.rb, line 17
def self.remove_methods!
  ((private_instance_methods + instance_methods) - KEEP_METHODS).each{|m| undef_method(m)}
